Specification forming part of Letters Patent llo. 93,985, dated August'24, 1869.

- To all whom itmayconcern: H i Be it known that I,VN.F.YGILMAN, ofRochester, in the county of Olmsted and. Stateof Minnesotapha-veinvented a newanduSeful.

Im novement in Grain Binders; and 11 do hereby declare thatthefollowing-is ,a full clear, and exact description thereof, l which.

will enable others skilled in the. 1 artito u 1 ake and 'use the same,reference beinghadl, to the accompanying drawing, forming part of thisspecification, in which V Figure l is a front view, of iuy improved natchine, parts being broken away to show the; construction. Fig. 2 is atopview. of the same.

Fig. 3 is an endiview of thesameqn I Similar letters of referenceindicate correspoliding parts.

My invention has for its object to furnisliau improvement in the methodof binding grain as, it is cut by a reaper, by, means of an appa{ ratuswhich shall be simpler than those usually applied, requiring-a'machineryless (idl lpleir, and, consequently, less liable to; get out of orderfrom the roughnesslof thegrain-field;

and it consistsin the mannerof binding the i,

on the front longitudinal bar of .the frameA,

and the rear part of which is supportedoy the cord or chain D, one endof which 1s attached to the rear part of the said platform, and theother end of-which is attached to the-.windlass E, so that the saidplatform may be adjusted as desired.

The Windlass E is provided with a ratchetwheel and pawl, 6 0 so that'itmay be held securely in any desired position. F is a pulley attached tothe shaft G, which receives motion from the drive-wheel B by a bandwhich passes around a pulley attached to said drivewlieel, and whichshould be provided with a tensionpuiley to keep it taut, however theplatform 0 may be adjusted. V

The shaft G revolves in hearings in supports attached to the platform 0,and to it is attachd a bevel-gear wheel, E, into the teeth of whichmeslr-sthe teeth of the bevel-gear wheel I, attached to the shaft J,which revolves in bearin gs insupportsattached to the platform (J. IheshaftJ is set in an inclined position,

andto. its inner. end is attached, or. upon it is formed,- a;cran-k, K,the crank-pin of which is connected wlithtthezndof the pitman L by aball-and-socket,joint.- .7 f Y The. pitmau L passes through a verticalslot in thevertical bar-.M, which is. pivoted to the supportingframe-work N by meansof rear- ,wardly-fprojecting arms 11; M2 as shownin Fig.

7 l. The forwardend of the pitmanL is hinged to the; lower 0, the lowerend of which .is

. fhinged .tothe lower end of the vertical barM, 1

andl-theupper end of which "is hinged to. the

. vlever ,P, To the upper end of the lever P is hinged the upper endvofthe bar or lever Q, ,the lower-endfof. which is pivoted to therearwardly-projectingv end of the arm m of .the verticaL, bar M. R;isthe rake head, to

Whichthe rake-teeth 'rare attached, and which is hinged at the loweredge of its middle part :to the lower end vof-the lever P, so that thesaid, rake-head R, while. sweeping the grain across, theplatform 0, maybeheld steady by,

resting uponithe re'ar side-Jof'the end of the Y lever-.15, as shown inFig. 1, and, at the same time, befreato fold upwhile passing back overthegplatformv G. r ;S isarod, the lower end 0f which is'pivotedtotheupper edge of the rake-head R, which passes up along the lever P,where it is kept'in place by a keeper, and to its upper end is attacheda cord, T, which passes through a hole in the said lever P, and

its other end is attached to the lever Q. The cord '1 should be of sucha length that when the rake-head is extended to the farther end of theplatform 0, the said cordwill be drawn taut, so as to extend therake-head into proper position to sweep the grain across the platform.

As the grain is swept across the platform 0, itv

is received and compressed by the arms U,

rigidly attached to the shaft V, which works in bearings attached to thesupporting framework N. To the shaft V'is rigidly attached arearwardly-projecting arm, W, to the outer end of which is pivoted thelower end of the connecting-rod X, the other end of which is pivoted tothe pitman L near the crank K, as shown in Fig. '1.

The bundles of grain are held from being they pass into areceptacle-prepared for their reception, and which is not shown in thedrawings. O is the hook, which'works up and down through guides attachedtothe vertical bar M. To the upper end of the hook G is adjustablysecured by a set-screw a collar, D, to which is pivoted the upper end ofthe bar E, the lower end of which is pivoted to the bar or lever 0, sothat the said hook may be operated by the movement of the rake.. F is ahook attached to the lower end 'of the bar or lever 0. c is a small stoppivoted'to'the hook G, which, when down, covers the point of the hook,and enables it to be drawn through the loop, and, when, raised, uncoversthe hook, so that it may catch upon the cord and draw it throughthe'loop. G is thebinding-cord, which is wound upon spool, H, placedupon a spindle, 1, at the rear side of the platform '0, and held so thatthe cord ,G may have the requisite tension-by. a-coiled spring, J placedupon said spindle, and adjusted with the nut K.

In using the machine, as the hook 0 begins to rise, it is moved forward,so as tocatch upon the cord stretched acrossthe hole in the platform 0,into-which said hook enters. 'As the hook O rises, the cord G slips overthe hook F, which moves forward to receive it,

' forming the loop. At the same time, the grain to be bound is sweptinto place by the r'ake'lt, and is compressed by the arm-s U. As thehook again descends, itpasses through the loop upon the hook F, whichraises the stop c ,so that the hook may again catch upon the cord anddraw it through the loop, drawing it from thehook F, and again slippingthe cord over said hook F to fornrthenext loop.

By the peculiar arrangement of the bars and levers by which the rake isoperated,-the said rake, as it moves back, moves to the rear side of theplatform, until it reaches the farther ends ltthen moves forward alongthe part of the platform upon which the grain lies, sweeping the saidgrain into position to be bound. L is a guard attached to theplatform-frame at the fartherwend of said platform, to prevent the'graiufrom falling so close to said end as to interfere with the forward move-IDGIItOf the rake R. In this way a series of bundles, looped together,is formed and collected in the receiver. When the receiver is filled,the binding-cord is cut and the receiver 1 emptied for the reception ofthe next series of bundles.

Having thus described my invent-ionfwhat I claim as new, and desire tosecure by Letters Patent, is-' v 1 f Z.

1. The pitman L, connecting the crank; K

r with the bar or lever P, carrying the rake-head,

whenarranged to play up and down within the vertical slot of. theupright bar M, asher'ein described, :for the purpose specified.

2. The combination of the rod S and cord y T with the hinged rake lieadR, lever P, and bar or lever Q, substantially as hereinjsho'wii anddescribed,and,for' the-purpose set forth.

3. The adjustable book 0, bar or levr'Ef,

and hook F, constructed and operating in combination with the vertical.pivoted bar M- W m and lever 0, substantially as herein shown anddescribed, and for the purposeset forth. I

4. The arms U, shaft V, arm W, connectingrod X, and springs Y and Z,-incombinatiouwith the pitman L and rake R, substantially as herein shownand described, andfor the purpose set forth. 5. Binding grain. in aseries of coniiected bundles, by a continuous looped cord,.sub.stantially as'herein shown and described.
